Specification of Letters Patent. Application filed September 7,1907. Serial No. 391,780.

Patented Dec. '31, 1907..

To all whom it may concern:

Be it known that I, BYRonSTEvENs, residing at Oakland, in the county of Alameda and State of California, have invented certain Improvements in Turbine-\dotors, of which the following is a specification.

The present invention relates to turbinemotors, by means of which the energy of steam or other'elastic fluid under pressure is converted into mechanical power.

' In carrying out my invention I provide a turbine motor having a pair of wheels, one of which is revoluble while the other is stationary, each having thereon an annular series of blades, one of said series bein located inwardly from the other so that t e blades of one wheel are concentric with, but oppositely disposed to those of the other, the series of blades being of such a diameter that there is provided centrally of the same a chamber connected to an intake-pipe, through which a stream of fluid may be caused to flow radially against said blades, being directed there- 'to by a series of openings in the stationary wheel, thereby causing the revoluble Wheel to move away from the stationary wheel.

The invention also consists in certain de- )tails of construction, all ofwhich I will proceed to describe and point out in the appended claims. a

Of the accompanying drawings-Figure 1 is a side view of the turbine motor partly in section, and Fig. 2 is a section on line :r-x o Fig. 1.

In the drawings, a is a base-plate to which are attached the standards I) b, which support the cylinder 0, closed at one. end It and open at'the other end. The closed en'd is perforated centrally to provide a bearing for a shaft 7 and is made tight by means otthe stuffing-box d, and the outer portion of the shaft is supported by the standard g. The standards 6 b, and g, as well as the cylinder, are represented as being integral with one another, but may be separated and bolted together, in a manner well understood.

The open end of the cylinder is closed by the disk 6, provided with the lugs 16, which register with the lugs 15 on the face of the cylinder, and the lugs are joined by the bolts 27) In practice, the joint between the cylinder and the disk is sealed by a gasket. Extending outward from the center of the disk is a pipe 1 provided with a collar 2 by which the pipe may be extended by a con nection 3 to the source of compressed fluid.

The disk 6 is rovided on its interior face with a series 0; concentric tubes 17., separated by the s aces 22. These tubes are represented as raving three series of openings 23' through the same; those in the inner tube 17 are straight 28, and at an angle to the radial lines-there0f, and We the initial direction to the fluid, while t e openings 23 inthe other tubes are curved. The openings 23 are shown as divided by partitions '19 into a series of'three, but maybe divided into any suitable number.

The shaft 7 is joined to a disk f on the inside of the chamber 6, and the disk is .provided on its interior face with a series of concentric tubes 9 separated by the spaces 10, and these tubes have three series of curved openings 11 through the same, but which are curved oppositely to the curved openings 13 in the tubes of the disk 6. These openings are divided by partitions 12 into a series of three.

The disk c with its concentric tubes conwith its concentric tubes forms a movable wheel, and the tubes of each wheel enter the spaces of the other so that the series of openings may be called blades, as they constitute the parts upon which the compressed fluid impingesto cause the movable wheel to rotate wlth the shaft 7, to which may be attached any tool to perform the work, or a wheel from which ower may be conveyed.

At the lower si e of the exhaust chest 6, is a waste-pipe 4 having a collar 5 to connect with an extension to convey away the exhausted fluid. By locating the exhaustpipe at the lower'end ofthe chest 6, all condensed fluid will flow away by gravity.

The operation of the turbine-motor will be apparent to one familiar with the art. The compressed fluid enters by the intake 21, be ing regulated thereto by a governor m hereinafter described and comes to the central chest 20 from which it flows by the initial direction passages 28 in the stationary wheel, into the openings 11 and 23 of the movable and stationary wheels to the exhaust chamber 6 and pipe 4, translating in its passage therethrough its energy into motion; and as the movable wheel revolves, the fluid alternately flows against its blades and is cut off and allowed to expand, all in a well understood manner, until its energy is gone.

I claim a particular advantage in the construction of the turbine-motor here describ ed,

in that there is one stationary wheel with the use of a central chest into which then-fluid at its greatest pressure is introduced and caused to: pass radially, in all directionssimultaneously, and so cause the pressure of the fluid to be felt-upon the entire peripheries of the cylinders and blades of the mov able Wheel.

By means of the central chest a centralized' motor construction is secured, and the ener 1s simultaneously and? instantly applie to all the o enings of the wheels.-

closing the concentric cylinders, may be made in many different ways, to support the various parts. I ,j

The overnor M consists of the tube *0 provide internally with a spider m in which is bolted to turn therein theend of rod m provided at its opposite end with a screwthread which on ages with w an internallythreaded boss m m the pipe 1, and has upon its outer end a 'Wheel an, by which the rod and cylinder at are moved back and forth. When the governor is in the position shown, the full force ofthecompressed fluid can pass through the tube n to the blades of the turbine, and by turning the Wheel m the cylinder n is pushed inward and the fluid is shut off from the blades in any degree desired.

A peculiar advantage is obtained by the use 0 the tubular valve 12,, as the full force of the fluid is always carried into the chest 20,

position of the valve a.

so that whatever the full head or pressure 0 the fluid passes tothe blades without being diminished, as is the case by the use of a throttle-valve or go'v- I claim as my invention, 1. In a turbine motor, the combination of one side, a rotatable disk in the casing on the end of the shaft close to one wall thereof having a series of concentric tubes provided with openings or blades on the inner face of said disk, a second series of concentric tubes with openin s or blades connected to the opposite we] of the casingthe inner tube of which'incloses a chamber extending to the face of said disk 'on one end and communi: cating at the "op 'osite end with an intake or suppl pipe, wit a slide valve in the p1pe.

' 2. in a turbine motor, the combination of a tubular casing, a shaft entering the same on one side, a rotatable disk in the casing on the end of the shaft close to one wall thereof having 'a series of concentric tubes provided said-disk, a second series of concentric tubes It will be un erstood that the casing in-;

withopenings or blades connected to the opposite wall of the casing the inner tube of which incloses a chamber extending to the face of said disk on oneend and communi-' eating at the 0p osite' end with an intake or supply pipe, a s ide valve in said pipe, with a peripheral space of the casin surrounding said tubes provided with an e aust pipe. 3. In a turbine motor, the combination of a tubular casing, a shaft entering the same onone side, a rotatable disk inthe casing on the,-

end of the shaft close to one wall thereof having a series of concentric tubes withopen ings or blades connected to the 0 posite wall of the casing interleaving with tlhe tubes of the first series, its inner tube enterin said chamber and forming its circular wal, the

, centralface of said disk being an end wall of the chamber, with a supply or intake, pipe communicating with the opposite end of the chamber providedvwith a slide valve.

In testimony whereof, .I have signed my name to this specification in the'presence of two subscribingwitnesses, this26th day of August 1907 v BYRON STEVENS.
